Espresso Hand Grinder? Testing Comandante MK3 Nitro Blade

Since a couple of days ago it came to be I’m a thankful user of Comandante MK3 Nitro Blade hand grinder. Until these days I’d used each Comandante grinders (MK2 and MK1), and I additionally ran the Hand grinders test season that is last. Even though I haven’t met Mr. Bernd Braune, the CEO of Comandante, we talked about the grinders of his and the shows of theirs a couple of times by Facebook or email.


Comandante is a German manufacturer of hand-operated grinders. The organization objective is providing excellent hand mills for Speciality coffee. Mr. Braune previously said: “There are 2 things that are important in the life of mine: well made tools and fresh coffee! … There’s no time for fragile plastic stuff”. That’s precisely why, after the company’s start, they used only stainless burrs instead of the ceramic ones.

Stainless steel grinder core geometry “cuts” through the beans and provides a better grind result with a lot less undesired coffee dust. Ceramic burrs work with increased squeeze and push action. This time Comandante used extra steel and that is extremely inert and accomplishes the neutrality leading to good fruity notes and acidity that regular steel “takes away”.

The Comandante C40 MK3 Nitro Blade is a strong, high end grinder with an enhanced burr design. In the program arrives, aside from the grinder itself, an additional brown glass jar with a lid. The one thing I missed was a bag for transportation.

The burrs

The burrs are made with high-alloyed, high-nitrogen stainless steel with a fine martensitic matrix. Comparing to MK2 or MK1 the geometry as well as the structure had been refined to get the very best grinding performance.

As consequence of use of the correct information, the MK3 burrs are a slice of very wear resistant machine particle, with a significant level of edge retention. It provides it with the great benefit of stamina if dropped on the floor, in that case ceramic burrs may break or even obtain broken otherwise. MK3’s burrs are going to remain untouched.

I must confess that there’s an obvious enhancement in terminology of quickness and also fluency comparing to the prior versions. Actually a kid or even an elderly individual will manage to grind light roasted espresso beans. Grinding is stepless and smooth very. As a good example I ground fifteen grams of coffee for a morning filtration system in aproximatelly 25/30 secs. To grind the very same quantity of coffee for a morning espresso requires aproximatelly 40/45 secs.

Clearly, it depends upon the coffee we use. It is going to be faster with much more developed coffee compared to light roasted one. What I likewise discover a good improvement is definitely the quality of the burrs which lets us totally close the gap between the burrs. Which means that with Comandante C40 MK3 you are able to grind beans for any Czezve/Ibrik method also as for Espresso.

Coffee: Ethiopian Bifdu Gudina, Berlin, Five Elephant, Germany
Amount of coffee beans: ten beans
The amount in the top = grind size adjustment – number of turns of the adjustment screw (2,4,6,… clicks together with the 3 edged star dial) The amount at the end = grind throughput – number of turns.


I admit I was previously impressed with the prior Comandante grinder that was outstanding. The Comandante MK3 is in the opinion of mine one of the better hand grinders I’ve previously used. It’s really strong, the grind result looks incredibly precise & extremely consistent together with the minimum amount of coffee dust, or maybe considerable amount of coffee boulders. The steel surface is inert and subsequently does with complete sensory neutrality.
